My starting summon is a small skeleton - Chapter 202 - 199 Final Trial

The MC entered the body of the An family eldest son, An Ziran, an arrogant 16 years old boy who weighed 78 kg (~171-172 lbs), who only knew how to eat, play and sleep. Seeing his current body, An Ziran decided his first priority was to LOSE WEIGHT!

Three days later after he became An Ziran, An Ziran’s father and his biological mother died, which meant as the eldest son he had to take over the family business.

Beside his legitimate first wife, An Ziran’s father also married 3 others women, who all wanted to take over the An family fortune but only the eldest son could be able to touch it, therefore they have to depend on An Ziran in order to live a comfortable live.

An Ziran’s father also had an older brother who is always planning to steal the An family fortune. The elder brother of An Ziran’s father and the woman he married had powerful connections. In order to save the An family fortune, An Ziran has to find a golden thigh to cling on. The butler told An Ziran that there is an engagement between the An family and an influential family. Therefore he takes his sister to that family house to make a connection.

However, during their journey, An Ziran’s younger sister overheard that the son of that family is UGLY, so as a beautiful and spoiled young lady coming from a rich household, she didn’t want to marry him and decided to run away. Without any other choice, An Ziran had to take his sister’s​ place and marry that man, who told him that he would let him go soon, but lied.

“Look at him,” someone snickered from a few rows over. “Smells like he sleeps in a dumpster.”“Probably does,” another voice added, louder this time. Nox just stared at his textbook, the words blurring. He had heard it all before.Then, Mark, one of the main reasons his life was a living hell, swaggered past his desk. Mark always had a smirk on his face. “Oops,” he said, not even trying to sound accidental, as a full cup of bright orange juice tipped over, splashing all down the front of Nox's already ruined shirt. The cold liquid soaked through instantly. Laughter erupted around the room. It was loud, clear, and mocking. Nox slowly looked up. His eyes landed on Ms. Joy, who was watching the whole thing. She had seen Mark deliberately pour the juice on him. He raised his hand, a small, tired gesture. “Ms. Joy,” he said, his voice flat. “He just poured juice on me. Are you just going to ignore it? Again?.” Ms. Joy looked at him, then at Mark, who was now theatrically wiping his hands. A small smile played on her lips. Then she chuckled. Just a little airy laugh.“Oh, Nox, don't be so dramatic. Boys will be boys, right Mark?” Mark puffed out his chest. “Yeah, Ms. Joy. He's just sensitive.” The class laughed even harder at that. Ms. Joy joined in, her laughter ringing out with theirs. Hearing them all, hearing her laugh, something in him finally snapped. It wasn't a loud break, more like a quiet, final click. He realized it then, with a cold, hard clarity. No one was coming to save him. No teachers, no police, no parents he never had. No one cared. If he wanted this to stop, he would have to be the one to stop it. He was the only one who could.His face remained blank, but his mind was suddenly very clear. He reached down slowly, his hand going into his worn-out school bag. The laughter died down a little as a few students noticed his deliberate movement, a strange stillness about him. He pulled out a gun.The classroom went silent. Utterly, completely silent. Mark's smirk vanished, replaced by wide, terrified eyes. Even Ms. Joy stopped laughing, her face paling. “What… Nox, what are you doing?” she stammered, her voice suddenly shaky. He didn't answer. He looked around at their faces, one by one. Fear. He saw fear now. Good. He was ready. He was going to make them all pay. He was going to end it, all of it.Just as he was about to raise the gun properly, a bright blue screen appeared right in front of his face. It was translucent, and only he seemed to see it.
